Burt Stein, business manager of the lead singer of heavy metal band Motley Crue, has filed suit against the band in Nashville's federal court. He accuses the band and its management of trying to cut him out of the percentage of revenues he has shared in for many years.

In his legal complaint, available at this link, Stein claims that band manager Allen Kovac has been threatening to sue him over the 1.875 percent cut he receives from the band's earnings as the personal manager of Vince Neil, the group's lead singer.

Kovac and the band did in fact file suit against Stein in Los Angeles on Wednesday — the same day Stein filed his lawsuit. Celeb-watching website TMZ.com broke the news broke news of that lawsuit soon after it was filed.

The two sides portray Stein's relationship with the band differently. Kovac's lawsuit says Stein used to manage the band itself and that he is entitled to nothing now that the band has switched to a new manager. Stein calls himself Neil's manager, and press accounts indicate that he has occupied that role. Stein even reportedly served as best man in Neil's wedding.

Motley Crue sued another manager last year over alleged misappropriation of funds. Filings in that case indicated that the band's revenues have at times reached $30 million a year.

Stein heads the Nashville office of the major talent management firm Gold Mountain Entertainment, which manages such acts as Nanci Griffith and Ronnie Milsap.

None of the parties could be reached for comment today. Sam Lipshie and Colin Carnahan of Boult Cummings in Nashville represent Stein.
